BOILER.

SPECIFICATION forming part. of Letters Patent No, 334,277, dated January 12, 1886.

Application filed November 5, 1885. Serial No. 181,883. No model.)

To all whom it may concern:

Be it known that I, WILLIAM C. PENNooK, of Oardington, in the county of Morrow and State of Ohio, have invented certain new and useful Improvements in Boilers; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings,which form part of this specification.

My invention relates to animprovement in boilers; and it consists in the combination of the shell of the boiler, the fire-box or flue, the bonnet connected thereto, the return-flues, the outer head of the boiler, and the smokebox, all of the parts being connected together so that when the outer head of the boiler is detached therefrom the other parts can be readily removed for the purpose of repairs or being cleaned.

The object of my invention is to so construct a steam-boiler that all of the parts which are placed inside of the shell of the boiler can be easily removed, as in one solid piece, giving free access to all of the parts of the boiler for any purpose desired.

Figure 1 represents a vertical longitudinal section of a boiler embodying my invention. Figs. 2, 3, and 4 are detail views of the same.

A represents the shell of the boiler, which is made of any construction that may be preferred. Upon the outer end of the shell is secured the angular flange B, and upon the outer head, S, of the boiler is secured a corresponding flange, B. WVhen these two flanges are brought together, suitable clamping-bolts, or other equivalent devices, are used for securing the head of the boiler in position. Through this outer head, S, of the boiler is made a large circular opening for the end of the firebox or flue F, and a number of smaller openings, through which pass the outer ends of the return-fines T. The head S of the boiler is flanged where the fire-box or flue passes through it, as shown in Fig. 1, and this firebox or flue F is secured to this flange by rivets, or in any other way that may be preferred.

To the inner end of the fire-box or flue F is secured the circular plate 0, which has perforations made through it corresponding to those made through the outer head, S, of the boiler, and into these perforations are passed the inner ends of the fire-box F and the return-fines T. This circular plate 0 is also flanged around the large opening, into which thefire-box F passes, so that this plate 0 and the fire-box can be fastened rigidly together. The bonnet D is secured to the plate 0 by means of the angle-iron H, as shown.

The products of combustion pass from the fire-box or flue F into this bonnet D, from which they pass through the return-fines T. The joint between the plate 0 and the angleiron H being exposed to the action of fire, a copper casket should be used.

To the under side of the fire-box or flue F is secured a suitable truck, R, the wheels of which run upon a track, I, which is formedin the bottom of the boiler.

The outer end of the flue or fire-box F extends a suitable distance beyond the outer head, S, of the boiler, and upon this outer end and the head of the boiler is secured the smoke-box P, as shown. Through thissmokebox is made an opening,which is covered by means of the door L, for the purpose of giving access to the flues T; also hinged upon this box is a door, 0, which closes the mouth or outer end of the fire-box or flue F. In this flue F are placed the grate-bar G and the bridge-wall N.

The outer head, S, of the boiler, the smokebox 1?, the flueor fire-box, the bonnet D, and the return-fines T being all rigidly connected together, as here shown, and the inner end of the flue F being supported on wheels, it is only necessary to remove the clamping-bolts from the flanges B B when the whole interior part of the boiler can be readily drawn out for the purpose of being cleaned or repaired, as may be found necessary.

Having thus described my invention, I 9 5 claim- -1. The combination of the outer shell, the outer removable head, the smoke-box, the fire-box having its outer end project beyond the outer head, S, and having a truck placed under its inner end, the return-fiues, and the In testimony whereof I affix my signature bonnet D, substantially as shown. in presence of two Witnesses.

2. The combination of the shell A, the outer T removable head, S, the smoke-box P, the fire- WILLIAM PHNL 5 box F, having its outer end project beyond \Vitnesses:

the head S, the return-fiues T, and the bonnet GEO. P. STILES, J12, D, Substantially as set forth. E. J. VAUGHAN.
